6.2 Managing Dynamic Lists

6.2.1 Editing a Dynamic List

  1. Launch the Sentinel Control Center. For more information, see Step 1 in Section 6.1.1, Using the Sentinel Control Center to Create a Dynamic List.

  2. Launch the Dynamic Lists window:

    • (Conditional) If the Configuration menu is not enabled, click the Configuration tab, then click the Configuration menu > Dynamic Lists or click the icon in the toolbar.

    • (Conditional) If the Configuration menu is enabled, click the Configuration menu > Dynamic Lists or click the .icon in the toolbar.

  3. In the Dynamic Lists window, select the dynamic list you want to edit, then click View/Edit.

  4. Make the necessary changes, then click OK.

    The name cannot be changed.

    NOTE:If you make changes to the transient life span on an active Dynamic List, the changes do not apply to elements already in the list. Elements that are already in the Dynamic List retain their original life span.

6.2.2 Deleting a Dynamic List

You can delete only the dynamic lists that are not being used by Correlation rules or actions:

  1. Launch the Sentinel Control Center. For more information, see Step 1 in Section 6.1.1, Using the Sentinel Control Center to Create a Dynamic List.

  2. Launch the Dynamic Lists window:

    • (Conditional) If the Configuration menu is not enabled, click the Configuration tab, then click the Configuration menu > Dynamic Lists or click the icon in the toolbar.

    • (Conditional) If the Configuration menu is enabled, click the Configuration menu > Dynamic Lists or click the .icon in the toolbar.

  3. In the Dynamic Lists window, select the dynamic list you want to delete, then click Delete.

  4. Click Yes to confirm deletion.

6.2.3 Removing Dynamic List Elements

There are several ways an element can be removed from a Dynamic List:

  • The element can be removed manually:

    In the Dynamic List Properties window, select the element you want to delete, then click Delete.

  • The element can be removed by a Correlation rule action.

  • The element‘s life span can expire.

  • If the maximum number of elements for a Dynamic List is reached, elements are removed from the list to keep the list at or below the maximum list size. The transient elements are removed from oldest to newest before any persistent elements are removed.
